Jack, Phals like warm weather, but when it gets hot, they need to be
protected from the sun, and the roots like to be misted.
Misting in the AM is not enough for Phals in such heat. I dunk all my
mounted phals into water and let them sit for approximately 10=15 minutes
every morning (unless it rains). And even when it rains, if the forcast
calls for dry afternoon, I water the mounted Phals. I suspect that yours
are dying of thirst and got a bit of sun burn!

I got a phal at my local OS about 6 mo ago. I live in the San Fernando
Valley (Los Angeles, only hotter). Everything was stable, even sprouted a
new and hefty root. I mounted it and moved it to my patio where it gets
bright shade for long periods. Been pretty hot here lately 100F to 105F
by
2pm. The other day I noticed that the lowest of 4 tiers of leaves had
turned brown and withered. I figured, well, ok I read that some Orchids
are
desiduous. No worries, but now only about 5 days later the next tier (2
leaves) are doing the same. As a precaution I moved it back inside.
Everything else seems healthy, the roots and the other leaves have good
color and feel. So is this normal desiduous behavior or is it just too
blinkin hot. I mist the moss daily in the am, sometimes twice. BTW there
are 4 other mounted orchids of various types on the patio in a group, seem
to be fine.

Got $.02 for me?
